Pin Tumbler
The pin tumbler lock is the most common mechanical locking mechanism in North America for residential deadbolts, commercial mortise cylinders, and padlock housings.
Wafer Locks
Wafer tumbler locks utilize flat spring-loaded metal plates (wafers) rather than round pins. They are common in low-to-medium security applications due to their compact form factor and cost efficiency.
Tubular Locks
Tubular locks (also known as ace locks or radial pin tumbler locks) arrange their pin chambers in a circular pattern around a central solid post, matching the circular key format.
Interchangeable Cores
Interchangeable cores (IC) are modular lock cylinders engineered to be extracted and replaced in seconds using a specialized Control Key without disassembling the surrounding lockset or door hardware. They are the standard for commercial office buildings, universities, hospital networks, and financial institutions.
Safe & Vault Locks
Mechanical combination safe locks protect commercial safes, bank vaults, and government security containers. Unlike key-operated cylinders where pins move linearly, mechanical safe locks utilize a rotating wheel pack and fence mechanism that operates entirely through angular rotational tolerances.
RFID & Contactless Access
Radio Frequency Identification (RFID) and contactless smartcard mechanisms govern the transmission of identity credentials over air interfaces. Understanding modulation schemes, framing architectures, and cryptographic handshakes is essential for assessing electronic access control security.
